It sounds like your onboard RAID chip is either not supported, or the appropriate driver is not being loaded. Can you post the output of dmesg? Also, be aware that you may not really have a hardware RAID chip. Many (most?) times the onboard chips simply make multiple disks look like a single LUN to the operating system; they also require driver support. Real hardware RAID chips/cards tend to be expensive, proprietary, don't require an OS driver and include a battery backup system for data in the RAID cache should the system lose power. You may want to read up on gmirror. -Damian ps. I've got at least a half-dozen different x86 system boards that include these crappy RAID chips from vendors like nVidia, Intel, Adaptec, LSI, etc. Typically you get closed-source, Windows-only driver support. pps. If you do want real hardware RAID support under FreeBSD, I've had great experiences with the Promise arrays (m500 and m300) and one of the PCI cards (I'd have to check on the exact model). _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
